This allows new types to be added without any fuzz (no need to specify the traits) if it has operator>>. It also removes the need to manually specify the ArgTrait for all built in types (such as long, bool, char, float etc). ArgTraits now works in the following way: 1) If there exists a specialization of ArgTraits for type X, use it. 2) If no specialization exists but X has the typename X::ValueCategory, use the specialization for X::ValueCategory. 3) If neither (1) nor (2) defines the trait, use the default which is ValueLike.
TCLAP - Templatized Command Line Argument Parser This is a simple C++ library that facilitates parsing command line arguments in a type independent manner. It doesn't conform exactly to either the GNU or POSIX standards, although it is close. See docs/manual.html for descriptions of how things work or look at the simple examples in the examples dir.
